GRANITE
The earth offers many varieties and qualities of granite
millions of years old. By no means would every variety
of granite be suitable. A soft or porous granite variety
influences directly the surface plate STABILITY and the
measuring surface DURABILITY.
THREE IMPORTANT PROPERTIES
As to structure, granite used for the production of granite
surface plates should satisfy severe qualifications, leading
to the following three important properties:
STABILITY OF TEMPERATURE
Due to a low coefficient of expansion (Fine Black
Granite 5x10-6, normal granite 7x10-6 meter per degree)
the expansion is low as well. Therefore our surface plates
are much more stable in temperature. Unequal temperature
– unavoidable in work places and measuring rooms
(temperature below and above) – changes the granite
surface plates much more, and as a result this influences
the accuracy of the surface more than Fine Black
granite surface plates.
1. Durability
2. Stability
3. Accuracy
FINE BLACK GRANITE
ADVANTAGES
Material
Structure Hardness
We use Fine Black Granite as our standard. This granite
has a very fine-grained structure and is homogeneous with
grain-size below 1 mm. Normal black, grey or pink granite
have a grain-size of 2-3 mm. The hard crystals of normal
granite are rough, the twined spaces weak and porous.
DURABILITY
The high homogeneity of Fine Black Granite
(density 20% higher than normal granite) results in
a hardness wherever measured (6,5 - 7 according to Mohs’
scale). The high homogeneity of Fine Black Granite
guarantees longevity and the highest conceivable
degree of accuracy and flatness.
Fine Black Granite is twice as good as normal granite,
due to the directional crystal within the granite, thus giving
a high bending strength. To obtain the same bendingstrength as normal granite, the plate would need to be
44% thicker. Fine Black Granite is fundamentally insensitive
to mechanical overloading.
CHEMICAL CHARACTERISTICS
The absorption of humidity of Fine Black Granite is as half
as much than of normal granite. Measuring instruments,
inspection equipment which are mounted on normal granite
tables can rust due to the absorption of the humidity.
Fine Black granite tables are a corrosion-free base
for your measuring equipment.
4
ACCURACY
The manufacturing and final inspection takes place in
temperature controlled rooms. All measuring equipment is
to national and international calibration laboratories
standards. Higher accuracies, e.g. DIN 876/000 are possible
on request. Measurement deviations for surfaces or lengths
amount to 1 micron per 1,000 mm in length and are carried
out to the German DIN-standard 876 or – at your request –
in every measurable accuracy.
General
MORE ADVANTAGES….
Totally corrosion free, non-magnetic and di-electric.
All surface plates can be cleaned. Top surfaces are matt
and therefore non-reflective. Smooth sliding of measuring
equipment and measuring constructions. Because of the high
flatness accuracy and density of the upper surface an air
cushion is created, on which the measuring tools can slide
across very easy.
A large carrying capacity is created by micro accurate lapping
of the measuring surface area. Through fine lapping of the
surface area, good slide qualities as well as long life and
required accuracy is achieved.
Fine Black Granite has a very fine-grained structure.
This grade is used especially when manufacturing high
accurate components and air bearing surfaces.
ACCURACY BY HAND IS IRREPLACEABLE
Precision measuring equipment gives very high accuracies by
careful manual labour, which achieves the ultimate precision.
The maximum accuracy – for example the flatness – of granite
surface plates and granite parts can only be achieved by hand.
With our experience for accuracy our experts lap the
measuring surfaces of granite parts precise up to 6 decimal
places. Due to the high accuracy achieved, an air cushion is
created, so that parts can slide easily across the surface and
gives excellent durability.

SERVICE OFFERED –
ALSO ON SITE! Calibration – Revision
In a production process it is very important, that machined
components are produced to the required tolerances.
Unreliable accuracy of
the surface plate results in:
• False information about the product
• Dimensional inaccuracy
• Uncommon product dimensions,
caused by unknown flatness deviation
Consequently, to manufacture defect-free products,
measuring must be carried out on reliable surface plates.
We calibrate and repair precision granite
from all manufacturers!!
On request we can measure your precision granite tooling
in your works and provide it with a test certificate. We also
have the facility to lap the plates at your works by one of our
experts.
A service, which will save you investment
costs and minimises the down time of your
measuring equipment!!

STANDARDS
The bending of granite surface plates is minimised, if
supported at 22% from the side (Bessel points). This 3-point
support (A) guarantees against the smallest possible defect
caused by bending. Surface plates bigger than 1,000 mm
need points 4 and 5 (B) for safety against tilting.
Standards of granite surface plates
according to the German DIN-standard 876.
Our standard specification is determined according to
DIN-standard 876, in grades 00, 0 and I, and on request,
in any measurable grade of accuracy. The flatness for
surfaces is described in microns per 1,000 mm.
The tolerance for surface flatness is calculated for:
L
Grade 00
2 µ + -------- 500

GRANITE CASTINGS
Article No. G-135
.
We have many years experience in manufacturing components
from a few kilos up to several tonnes in weight, and for a
wide variety of industry sectors including machine tools,
metrology, semiconductor, medical, photo-imaging, pre-press,
laser engraving and ship building. With its customers spread
across three continents, our experienced engineers can
offer help with all aspects of design.
Precision Granite Castings are produced by using
granite aggregates. Crushed, river washed, kiln-dried and
mixed with an epoxy resin system to form a casting which
can be moulded into complicated shapes. All necessary
threaded inserts, pipes, hydraulic pipes, etc., can be cast
into the component to an accuracy only dependent upon
mould manufacture.

Precision Granite Castings give the
following distinctive benefits:
• Reduced assembly costs
• Competitive price
• Excellent vibration damping
(8 to 10 times better than cast iron)
• Improved thermal stability
• High strength to weight ratio
• High static, dynamic, torsional stiffness
• Excellent noise absorption
• Minimal post-cast machining
We will work with your company closely from concept
through detailed design to finished casting if required.
Metrology tables, columns, precision ground, to accuracies
of less than 2 µ can be achieved. Machine tools like milling,
grinding, boring, lapping, drilling, etc. can all benefit from
a precision granite cast bases.
Steel fabrications for bed structures and columns often
prove not stiff enough statically and dynamically, taking
into consideration the demands for increased performance
of todays’ machines. In certain cases the use of Precision
Granite Castings may not be economical because of small
production runs, mould costs or some other technical
constraints.
In this case an inexpensive method of filling the welded
fabrication with Granitek material is used to give the
advantages you would expect from a Precision Granite
Casting. Examples of Precision Granite Castings are too
numerous to list them all.

PRECISION LIGHT WEIGHT
GRANITE SURFACE PLATES
Article No. G-140
Light weight surface plates in Impala granite. Because of
a structured construction, in which several plates out of
granite are glued together, it is possible – in comparison
with solid plates – to gain a weight reduction of 40 to 60%.
Another essential advantage can be a faster adaptation in
temperature, especially in an environment with great thermal
differences.

Cast Iron
MARKING OUT TABLES IN
SPECIAL CAST IRON
Article No. S-900
Marking out tables are distinguished by their highly
dense and even surface structure. Exceptional strength
and durability of the surface are guaranteed by a special
cast iron/steel alloy. The high stiffness and stability of the
plates is achieved by the special rib design with T-shape
reinforcements and controlled cooling process.
Providing the plates are stored and supported correctly,
subsequent distortion of the top surface of the plate is
eliminated due to the various finishing stages. The surface
of the plates can be finished to DIN 876/III, II or I.
The sides are machined square to the top surface.
On request the top surface of the plate can be marked with a
precise grid pattern of lines, or machined T-slots to DIN 650.
A special finish is also possible on the sides to facilitate
the fitting of measuring machines (see ‘Standards’-page
according to DIN 650; page 25).
Our supports on page 26 and 27 are recommended for the
installation of these tables.
Marking out plates with ribbing or solid construction
available from 200 x 200 mm.
On request we can take over the mounting or clamping
activities as well.
Traceable test certificates to (inter-) national standards can
be offered.
